To all fwzom t may concern -151e it lmown that l, ARTHUR (l. llenne, e.citizen of tbe United States, and n resident of Amityville, in thecountv oit Sntioll and `State 'of .New York, lieve invented e new thebranches, the switch boingcontrolled bj1 the pressure in n, pipeextending tlirocgli the tank, and by tbe pressure 1n one ot thebranches.

Additional objects of tbe-invention will appear iii the followingcomplete specilica.- tion, in Wbicb tbe preferred form of my inventionis disclosed.

In tbe drawings similar characters of ret I erence indiceteycorresponding parte in ell sie Y e chamber 2'? in e. Switch member a"thev views, in which* 4 Figure A1 `1s a diagrammatic view of utbeinvention, the tank and one of the switch .members being shown insection; Fig. 2 is" an enlargedsectional View of one oi tbe switchmembers, and Fig. 3 is-an enlarged sectional view of the valvecommending the branches. i l,

.By referring to tbe drawings i.I will be seen that o 'tenir 5 is'provided having en inlet 6 :indien outlet "l, there being n check vulve8 in the inlet end :i check valve 9 in tbe outlet, a conduit 1G beingconnected with the tenir 5, tbe said conduit having tivo broncher-5.11and 12, wliiclfrare commended by the rotgoy valve 13. The branch 12 isopen to the etmospliere. The stem 140i tbe velvel has secured to it u.pulley 15, around which is disposed e cord 16, one end ci "which hes se#cured to it c weight 17, the other end being secured to tbe armature 18commended b a l the solenoid 19. Connected with tbe branch 11 of theconduit 1G, there is e. pine 2G, which 1 oo leeds to a Bourdon tube 21,switch or being carried by tliic Bourdon tube, end be. .ing adapted tccontact with tbe contact c.. points 23 and .fi pipe 25 ie. provided, oneterminal oi this pipe extending downwardly through tbe top 2o of 'thetenir tbe other terminal ci tbe pipe 25 communi..

side of tbe chamber 2T formed bv e. die..- phregm 29, the periplieryWliicb cured between flanges 30 of the switch member 28. A contact point31 is carried by the diaphragm 29, end is insulated therefrom by theinsulating-g materiel .A similar con 28, end "ivirisuleted therefrom bythe insu lating material 34:. Ai; will be understood,

with the Contact member 33, when the pressure in tlie pipe 25 'isSniicient to move tbe diaphragm 29 the required distance. in electricalconductor 35 is connected with the contact member 33, and an electricalAcon-` ber 31. The electrical conductor 36 is in electricalcommnniczition with the Contact member 37,. having e contact point 38,the said Contact point 38 being adapted to be engaged by a contact point39, on n Contact member 40 carried by one crm o1" the lever lil. TheContact member 40 is in electrical communication with the electricalconduit tricnl conduit 43 vconnects the electrical con doctor 35 withthe solenoid 44;. A svvitcli arm L15 is cerriedby the lever 11, end isadopted to contact with the contact points 46 end L17. The' 'solenoid14T is connected with the switch arm l5 by the electrical conduit L18.The contact point i7 is connected with vtbe contact point .23, by theelectrical conduit 49, and the contact point 16 is connected with theContact point 24 by an electricnl conduit 50.

ssliown in Fig. 3 of the drawings, o. cylindricel member 53 is securedto tlie'velve stem 14, 'there being en opening 51 in this cylindricalmember, adopted to eliord comn municntion between tbeV compartment 52 inthe valve leading to the branch 12, and the compartment 54 inthe valveleading tor the conduity 10. The cylindrical member elec bes econe-shaped portion forming' n. cemperi-ment having openinge or porte 5,and 5'?, which communicate with tbe coni-- 'pertmcnts and lintlie valve13, tbe compartment 58 communicating with the brnncb. 1l vtbecompartment 59 commu- .tbe Contact memberv 31 isndepted to Contactductor 36 is connected with the contactmem` 12,wl1icli leads to thesolenoid 19. The elec-I nicnting will 'tbe compartment 5i, end with Theelectric conductore Btl tect point Vis to the valve member the armature18 from the solenoid, and rotate the pulley 15, and the valve stern 14.AThis will open communication between the compartments 52 and 54 in thevalve, through 5 the opening 51 and the conduit 10 will com- .rnunicatewith the atmosphere through the branch 12. The tank 5 may then be illedby gravity, through the inlet 6. When the level of the water in the tank5 reaches a point above the terminal of the pipe 25, dis,

i posed in the tank 5, the air in the said pipe l 25 will be'compresscd,which will torce the f diaphragm 29 upwardly, so that the contact point31 will contact with the Contact member' 33. This will close the circuitformed byfthe electrical conductor 35, the Contact members 33 and 31,the electrical conductor 36, the contact members 37 and 40, with theirpoints .38 and 39, the electrical conv ductor 42 and the electricalconductor 60, which will energize the solenoid 19 which commands thearmature 18. The armature will be drawn downwardly by the solenoid,which will rotate the valve stem 14, and the cylindrical valve member53, so that com.

munication between the compartments 52 and54-will be cut oit", andcommunication will be permitted-between thecompartments 58 and 59. Whenthis takes place, communication between the conduit 10 and theatmosphere through the branch'12, will be cut oi, and ,communicationwill take place between the branch 11, and the conduit 10. This branch11 is in communication with a supply of air under pressure, ,and thiscompressed air will iiow into the tank 5 and force the sewage and watertherein out through the outlet 7. During the period when the tank 5 wasiilling with water and 9 sewage, the switch arm 22 was held inengagement with the contact point 23, by the compressed air in theBourdon tube, supe nplied by the branch 11. llVhen the tank has b`eensuiciently emptied to permit the con1- pressed air to escapequicklythrough the outlet 7, the pressure inthe branch 11 is reduced,and the Bourdon tube 21 is actuated, which draws the switch arm 22 awayfrom the contact point 23, Aand into engagement with the contact point24. Then this takes place, the circuit will be closed from theelectrical conductor 35, through the solenoid 44, the electrical conduit48, the switch arm 45, the Contact point 46, the electrical 5 conduit50, the contact point 24, the switch arm 22, the spring 61, and theelectrical conductor 62. This will. energize the solenoid 44, which willmove the lever 41 and will draw the switch arm 45 away from the con- 50tact point 46, and'it also moves the contact 40 away from the contactmember 37. This will break the circuit which has energized thesolenoid19, and as the armature 18 be* comes free from the influence of thesclenoid, the weight 17 and the cord 16 will draw the armature 16upwardly, thereby oper ating` the pulley 15, which is secured to valvestem 14. This movement of the valve will close communication between thebranch 11 andthe conduit 10, and will open communication between theconduit l0 and the branch As the pressure in the branch 11 increases, itwill operate the Bourn don tube, causing the switch arm 22 to move downand the contact point 23, closing the circuit 'formed by the electricalconductor 3.5,thc electrical conduit 43, the solenoid 44, the electricalconduit 48, the switch arm 41:5, the contact point 47, the electricalconduit 49, the Contact point 23, the switch arm 22, theelectricalconductor 62, and the electrical conductor 60. This will causethe -lever 41 to move son that the contact point 39 and the Contactn'icniber 40 will engage the contact point 38, so that the solenoid 19will again be energized when the water reaches a sutlicient heioht toairain com )ross c o the air in Athe pipe 25, and it will more theswitch` arm 45 out ot engagement with contact point 47 and intoengagement with contact point 46.

rllhere is an armature on Vthe .lever 4l which is commanded by thesolenoid 44, the solenoid when energized serving to d 1aw the armatureon the lever 41 to a center inertia, and the'spring 41'n serving' toino've the lever past t-liefcenter and A.into its opposite position.

The broad combination of elements herein including` asolenoid, anarmature commended by the soler i, valve mechanism commanding theconduit branches and means ccnnectin,g the solenoid with 'the valvemechanism 'forms a part of the subject-mat ter ci a separate applicationfor patent re newed byrme liiarch 14. 1912, No. 663,703.
